The Billets produced by the company can be broadly divided into three main types i.e.    

1.      M.S. Billets    

2.      CRS Billets     

3.      Special Alloy Billets   

M.S. Billets are used for rolling of TMT Re-Bars of Fe415 and Fe500 Grade and

various other structural steel products.     

CRS Billets are used for rolling of CRS TMT Re-Bars.    

Special Alloy Billets are used for rolling of any special grade TMT Re-Bars like

Earthquake resistant TMT Re-Bars and for special grade structural steel products.

Q:What is the drop per minute of the billet temperature at 850?
Cold rolling is not considered. The initial rolling temperature (surface) of the billet is generally 1000-1150 degrees.
Q:How are the billets classified?
The same type of steel, such as low carbon steel, the grade and composition design, but also look at the performance, therefore, a steel production process due to the abnormal quality, by the high grade and low grade sentenced to drop, but sales loss.......
Q:What is alpha carbon? What is beta carbon?
The method of marking C is generally used in organic matter, and the C atom directly connected with the functional group is called alpha carbon. The C atom separated from the functional group is called C beta atom, and alpha carbon and beta carbon are not unique
Q:What are the causes of internal cracks in continuous casting billet?
A French Research Institute of carbon, sulfur and phosphorus influence on continuous casting billet hot cracking, a total of three test groups of carbon manganese steel, carbon, sulfur and phosphorus content of each sample is different. The test according to the process of the sample for cooling, in order to study the effects of the three elements of the internal crack of continuous casting billet hot.
Q:What is carbon accumulation?
Generally refers to the polycarbonate, PC, is a kind of thermoplastic plastics, good transparency, good mechanical properties, surface hardness, common uses such as CD, plastic glasses, a fence, protective window, public places, vacuum cleaners, coffee machine, juicer barrel, refrigerator shelf, pure such as the bucket.
Q:Difference between billet, slab and billet
Production process of billet is through three methods: one is through the production of steelmaking and continuous casting equipment system, the molten steel is directly cast into the billet; two of steelmaking production systems of steel ingot or billet by rolling system of steel rolling equipment processing semi-finished products; three is the production of steelmaking system by forging semi-finished steel ingot the processing equipment. Market trends 1, domestic crude steel production remains high, although the domestic steel market has been relatively sluggish in recent times, and steel losses are more, but this does not seem to affect the enthusiasm of steel production. According to the China Steel Association statistics show that: in early April, the daily output of crude steel in key enterprises in China was 1 million 697 thousand and 300 tons, and the average daily output of crude steel in China was estimated at 2 million 123 thousand and 900 tons. And in mid April, crude steel daily output of ten days, although there has been a drop back, but still at a high level. According to statistics, in mid April, the average daily output of crude steel in key enterprises nationwide was 1 million 689 thousand and 100 tons, and the average daily output of crude steel in China was estimated at 2 million 115 thousand and 800 tons. Such a large production and sluggish demand in stark contrast, which is a drag on steel prices down one of the important factors.
Q:Use medium frequency furnace (1 million 500 thousand volt ampere) to produce 1 ton cast steel blank, how much kilowatt hour is consumed?
Look at the quality of scrap and the operation of workers, power consumption is generally between 550~650.
Q:Fish pole carbon cloth tcf. Vcf. Svf. Hcf. On behalf of what?
CF: is the abbreviation of Carbon Fiber in English, which means carbon fiber in ChineseCarbon fiber index for T (ton), ordinary carbon cloth is generally 20T-30T.Domestic ordinary carbon fishing rod material is generally 24T carbon fiber cloth. The higher the T value, the higher the strength and elasticity of the material.
Q:The role of carbon content in steels
Therefore, the carbon content determines the use of steel: low carbon steel (carbon content < 0.25%), commonly used as extrusion and stamping materials; carbon steel (carbon content < 0.6%), commonly used as mechanical parts; high carbon steel (carbon content > 0.7%), commonly used tools, tool and mould etc..
Q:What is the difference between continuous casting billet and cast billet?
but with high-grade continuous casting line (full protection casting, electromagnetic stirring, liquid stopper control) compared both have a big difference in the crystal, oxidation, surface quality.
